OSHKOSH, Wis. (AP) — The chancellor at the University of Wisconsin-Oshkosh is bringing his 40-year career in higher education to an end. Richard Wells has led the university since 2000 and says it's time to move on. He'll leave the university in August. Wells says he's most proud of his collaboration with other area colleges to create NEW ERA, an alliance to provide greater educational resources to the community. He says he's also pleased that UW-Oshkosh is now known as a leader in efforts to preserve natural resources. Wells says he's also proud of his work within the greater community, including a partnership with the city and the Oshkosh Area Community Foundation to rebuild the waterfront hotel. As for regrets, Wells says he wishes he'd had more success in bridging the achievement gap for minority students.
